Retrieve resource types from the cluster instead of hard coding them

[InfoSec812]

As a developer who works across a number of different Kubernetes cluster from a number of different vendors, and as a developer using Operators in K8s; I would like to have a way to convert existing resources of types not currently defined in this application.

For example, if using the Strimzi Operator for deploying Kafka clusters, I would want to be able to extract, templatize, and convert to a chart the Custom Resource Definitions for Strimzi.

Line 20 in 9322a89

type KubeObjects struct {

For example, on an OpenShift 4.2 cluster...

curl -s -H "Authorization: Bearer <REDACTED>" "https://cluster.example.com/openapi/v2" | jq '.definitions | keys'
